West Nile virus (WNV; family Flaviviridae, genus Flavivirus) is a member of the Japanese encephalitis virus complex, which also includes Japanese encephalitis virus, Saint Louis encephalitis virus
(SLEV), and Murray Valley encephalitis virus (1).
HI assays were performed by using Saint Louis encephalitis virus
(SLEV) antigen as previously described (9).
Usutu virus (USUV) is a relatively unknown member of the mosquito-borne cluster within the Flavivirus genus, closely related to important human pathogens such as Japanese encephalitis virus (JEV), Murray Valley encephalitis virus (MVEV), Dengue virus (DENV), Yellow fever virus (YFV), Saint Louis encephalitis virus
(SLEV), and West Nile virus (WNV) (1-3).
We used a dynamic hydrology model to simulate water table depth (WTD) and quantify the relationship between Saint Louis encephalitis virus
(SLEV) transmission and hydrologic conditions in Indian River County, Florida, from 1986 through 1991, a period with an SLEV epidemic.
